An addition in Vancouver means two permit paths, a stormwater threshold, and system development charges tied to the square footage you add — before a single footing is poured. Serden Group runs the whole sequence: feasibility against your zone, engineered plans, submittal, foundation, framing, roof tie-in and finishes. One licensed team, one project manager. Locally trusted since 2015.
Clark County housing stock runs from 1940s Northwest-neighborhood cottages to 2000s Salmon Creek and Cascade Park subdivisions, and each one fails a bad addition differently. Older homes have shallow foundations and framing that no longer matches dimensional lumber; newer ones have engineered trusses you cannot simply cut into and HOA architectural review on top of the city permit. We design the tie-in first — roof pitch, siding profile, window proportion, floor height — so the finished house reads as one building instead of a house with something stuck to it.
Bump-outs in Hazel Dell. Primary suites in Felida and Salmon Creek. Second stories where the lot has no room left. Garage conversions and ADUs permitted as separate dwelling units. Our own crew frames and finishes; licensed, vetted structural, electrical and plumbing partners are scheduled around them by one project manager.
Bigger family room, a fourth bedroom, a real dining space — footings, framing and roof tie-in on grade.
Bedroom, ensuite bath and walk-in closet added at the back or side, plumbed and vented properly.
When the lot is out of room. Engineered load path, shear walls, new stair, full roof rebuild.
Garage, basement and above-garage units permitted as legal dwellings — kitchen, bath, separate entry.
We confirm whether your address is inside Vancouver city limits or unincorporated Clark County — the two have different applications and different review — then measure your lot against your zone’s setbacks, lot coverage and height limits. You get an honest go, a build-up-instead recommendation, or a no, plus a realistic budget range before you pay for design.
Floor plans, elevations and stamped structural drawings, then submittal and plan-review management with the City of Vancouver or the Clark County Permit Center. We handle correction responses, the stormwater plan when a project crosses the impervious-area threshold, and the system development charges tied to added square footage.
Footings, framing, roof tie-in, mechanicals, then finishes — with your kitchen and bathrooms kept in service and the work zone sealed and dust-controlled. One project manager, daily progress, and a punch-list walkthrough before we call for final inspection.

Read all 400+ reviewsThe project was finished on time and within budget. There was outstanding communication from start to finish and meticulous attention to detail. They are a contractor that goes the extra mile and I would definitely recommend.
Fantastic experience! They renovated my entire home with new floors, a full kitchen remodel, and a bathroom upgrade. The kitchen looks amazing with new cabinets, countertop, and appliances, and the bathroom to shower conversion turned out beautifully. Great quality work, finished on time, easy to communicate with, and their pricing was very competitive. Highly recommend!
We were very happy with the workmanship on our upstairs, downstairs and stairs flooring. Very friendly and were very accommodating to our home schedule and would recommend them to anybody who needs work to be done in their home
Serden remodeled our kitchen, dining room, living room and entry way. Dennis and Alex were especially friendly and easy to communicate with. Every person we had contact with was professional and did quality work. When unexpected issues came up, they solved the problems efficiently so we didn't have to stress about anything. They worked really hard to make sure we were happy at each step of the process. We love our new living space!
I purchased my first home a couple years ago, which was a time capsule from the 60s/70s. I got multiple quotes on getting my house updated. I of course wanted the updates to be budget friendly, but quality enough to last for years to come. Serden Group helped make suggestions that saved me money (to no benefit to themselves). With some of the other quotes I received I couldn't understand where so much of the cost was coming from and the quotes themselves were not clear in what I was being charged for. Serden Group however was very transparent in their pricing. The work they did is absolutely beautiful. Communication was consistent and timely. Their crew is incredibly kind and professional and cleaned up everyday. I think the scariest thing for most people getting work done our their homes is finding a trust worthy company to do so. There are too many occasions of companies having inflated pricing, hidden expenses, shoddy work, or poor communication. If you're looking for a company you can trust and to treat your home with the best care, give these guys a call.
We have used Serden Team for 3 projects. They remodeled our master bedroom and bathroom, refaced kitchen cabinets and built a beautiful surround for my refrigerator so it looks built in and remodeled a secondary bathroom. Their work is fantastic. They are easy to work with and communication is the best. I can trust them to do a great job and do the work properly the first time. Wonderful company and will refer them gladly.
They did an excellent job. They were fast and professional. They installed all new doors throughout my house, raised the floor in my family room and office, installed new flooring, and painted both rooms. It looks wonderful. I will be so happy to use the rooms once everything is put back where I want it. We have more work we want done in the future and I will definitely be hiring these guys again.
Serden did a great job on my vacation home in WA. They transformed the property, I had all my floors and windows changed out. Everything looks beautiful, up to date and modern. I will be using them again to remodel my kitchen and bathroom. The whole experience was easy and quick.
We hired Serden and their team to do a complete remodel of our new home that was very outdated. The work they did was incredible! They were very professional, timely, and the attention to detail on the work is amazing. We are so impressed and highly recommend!
Thank you for your quick response. Also, a big Thank You for helping me make my dream house come true, I never expected my home to become so beautiful. Great job. I will recommend you to my friends.
Serden Group and their crews Had done an awesome job remodeling my house. I am very pleased with the outcome. They were very professional and on time. I would definitely use their service again and recommend them to families and friends.
The remodeling team from Serden Group did a very good and professional job at my home. They completely remodeled the kitchen and all the dining and living areas, everything looks like a brand new home! They also installed new patio cover and deck which we already enjoy. Thank you! I definitely recommend them, they are experts, friendly and know what they are doing.
Serden Group remodeled kitchen and all bathrooms in my house. I am very happy with the quality of their work and the way they were informing me on every stage of the project. They also provided design ideas and suggested colors and materials. I needed the full service from design to completion. I am very satisfied.
Cannot be happier with the outcome of our remodel! Professional and communicative contractors. We will go back to Serden for all of our remodeling needs, other contractors do not compare. Yes- we have wasted time and money on others, before finding Serden.
I recently worked with Serden Group on my condo renovation, which included replacing floors, removing popcorn from ceilings, and replacing kitchen counters and cabinets. I loved working with Dennis and David. Dennis helped with input on the kitchen design and was great in helping to reduce stress. They were patient with me and my questions. Their crew was great. And as messy of a job that it was, they managed to leave the place clean when they left for the night. The work was great, and they care for the space as if it;s their own.
This company did a great job on an extensive remodel of a mid 70s home. They upgraded the electrical, plumbing, removed walls, remodeled the bathrooms and kitchen, and put in all new tile flooring. All the home issues were addressed, and we could not be any happier.
This is where most Vancouver addition projects lose time. The rules are not complicated, but they depend on facts about your specific address — and getting them wrong costs weeks in plan review.
An address inside Vancouver city limits files a residential addition or alteration application with the city. An address in unincorporated Clark County goes through the county’s permit process for additional dwellings and structures, which covers additions, garage conversions, enclosing a covered patio, and ADUs. Neighboring streets can fall on opposite sides of that line. We confirm it against county mapping before we quote anything.
Neither the city nor the county sets one universal addition setback — the number comes from the zone your lot sits in, along with maximum lot coverage and building height. Published figures for Clark County zones commonly land in the four-to-ten-foot range from side and rear lines, but the only number that matters is the one for your zone, and we verify it in writing before design.
Washington law now requires Vancouver and many other cities to allow up to two accessory dwelling units on a residential lot, with ADU floor area generally capped at 1,000 square feet. That changes your application from an addition to a new dwelling unit, and it changes utility connections and charges. Our Clark County ADU permit guide walks the process in detail.
Vancouver requires a stormwater management plan once a project disturbs enough impervious area — a threshold even a modest bump-out with a new driveway apron can cross. System development charges are assessed on added square footage. Both are real line items, and both belong in your budget from day one rather than as a surprise at permit issuance.
Codes and thresholds change — Vancouver is expanding what is permitted on residential lots in 2026. We verify current requirements with the jurisdiction on every single project rather than working from last year’s notes.
From Salmon Creek and Felida to Cascade Park, Hazel Dell and Fisher’s Landing — Serden Group has built additions throughout Vancouver and Clark County. We know which addresses fall under the city and which under the county, what the Permit Center wants to see on a site plan, and how long review actually takes.
